Impedance Measurement of Small Antennas Over a Ground Plane Without Direct Cable Attachment
Antenna impedance measurement small antennas
2014/12/8
An indirect impedance measurement approach that does not require direct cable attachment or large space using a two-port network is presented. Using a straight wire monopole as an interrogating antenn...
High-Input Impedance Voltage-Mode Multifunction Filter with Four Grounded Components and Only Two Plus-Type DDCCs
Voltage-Mode Multifunction Four Grounded Components Two Plus-Type DDCCs
2010/12/3
This paper introduces a novel voltage-mode multifunction biquadratic filter with single input and four outputs using two plus-type differential difference current conveyors (DDCCs) and four grounded p...

Radiation Impedance Loaded Parallel-Plate Waveguide
2009/7/27
A hybrid method consisting of employing the mode matching method in conjunction with the Fourier transform technique is used to analyze the radiation of the dominant TEM-wave from an impedance loaded ...
Use of the Magnetic Field Generated by the Internal Distribution of Injected Currents for Electrical Impedance Tomography (MR-EIT)
Magnetic Field Injected Currents Electrical Impedance Tomography MR-EIT
2009/7/27
In two dimensional conventional Electrical Impedance Tomography (EIT), volume conductor is probed by means of injected currents, and peripheral voltage measurements are used as input to the reconstruc...
A Novel Generalized Impedance Converter Using Single Second Generation Current Conveyor
Active filters Current conveyors Impedance converters
2010/12/7
A generalized impedance converter (GIC) using single CCII(−) is presented. The circuit uses no matching constraints and provides a wide variety of ideal component simulators and multipliers. The...

Generalized impedance converters Transconductance element gm-C immittance simulation
2010/12/7
Novel generalised impedance converters are presented, which use only transconductance elements and/or grounded capacitors for the realisation of a wide variety of immittance functions. The generalised...
The Electrical Characteristics of Long Transmission Lines With External Forcing Impedance
Long Transmission External Forcing Impedance
2010/12/16
This paper presents a new idea for the radial type transmission line with external reactive forcing impedance at only the receiving end. The general constants of such line are deduced. The effect of b...
